The request read-only property of the
FetchEvent interface returns the Request that triggered
the event handler.
This property is non-nullable (since version 46, in the case of Firefox.)
If a request
is not provided by some other means, the constructor options object must
contain a request (see FetchEvent.FetchEvent.)
Implementation
external Request get request;
